Get rid of tabulations in the Java output.

Test 214 was failing: it greps with a pattern containing [    ]* which
obviously meant to catch spaces and tabs, but contained only tabs.
Tabulations in sources are a nuisance, so to simplify the matter, get rid
of all the tabulations in the Java sources.  The other skeletons will be
treated equally later.

	* data/java.m4, data/lalr1.java: Untabify.
	* tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
	tabulations are no longer generated.
